Much of what you will find on the Web is good quality information. Because there is so much out there, however, the quality sites may not always float to the top of your results list.

If you find a Web site and can't attest to its currency, relevance,
authority, accuracy or purpose, you probably shouldn't use it as a
source of information. There are many Web sites where this will be the
case.

The criteria discussed above will help you identify the quality sites that will enhance your research.

In the SEARCHING module, we talked about why Wikipedia may be a very
useful source, but not one that you will want to cite in your papers.

Not all sites will be as up front with disclaimers.

In fact, many sites exist as hoaxes to try to fool users. They may look legitimate at first glance, but the deeper you dig, the more questionable they become.
